For a 70 Kg patient: 110 ml/hr maintenance requirement. 1st 10kg is 4mL/kg = 40 mL 2nd 10kg is 2mL/kg = 20 ML remaining = 1 mL/ kg= 50 mL 40 + 20 + 50
63
calculate fluid maintenance for an 86kg man and what is his deficit if he has been NPO for 10 hours**
1st 10kg is 4mL/kg= 40 mL 2nd 10kg is 2mL/kg = 20 mL remaining 1mL/kg = 66 mL/kg/ HR 40 + 20 + 66 maintenance= 126 mL/hr deficit = 126 * 10 = 1260 mL deficit

howeverlong they are NPO by maintenance ex 70 kg man has 110 mL/hr maintenance= 880 mL deficit
66
how do you replace a fluid deficit
replace half the deficit the 1st hour and 1 quarter for the 2nd and 3rd hour then go to maintenance
67
What is the formula for calculating Allowable Blood Loss (ABL)?
(hgB initial - HgB allowable / HgB initial) x EBV ## Footnote ABL = (Hg initial - Hg allowable) x EBV / Hg initial.
68
what is EBV and how do you calculate it

69

Blood pressure, EKG, pulse oximeter, precordial, temperature.
71
How is ABL calculated?
ABL = (Hg initial - hg allowable) / Hg initial x EBW ## Footnote Example: Ex - 4900 x (13-8) / 13 = 1884 ml (ABL)
72
What should you monitor for signs of with ABL?

73
What are routine monitors used in anesthesia?
Blood pressure, EKG, pulse oximeter, precordial, temperature, capnography, nerve stimulator.
74
What is the history of noninvasive blood pressure monitoring?
Introduced in Italy by Riva Rocci in 1896; Harvey Cushing introduced it in the US.
75
What are common sources of error in blood pressure measurement?
Inappropriate cuff size and rapid deflation can lead to false readings. location of cuff
76
What is the correct size for a blood pressure cuff?**
Length should be 80% and width 40% of the extremity circumference.
77
what happens if a BP cuff is too small**
falsely high reading too big = false low
78
Where should a blood pressure cuff be placed for accurate readings?
The cuff should be at the level of the heart for the most accurate reading. ◦ Pulse goes from aortic root (SBP is lowest, DBP is highest) to periphery (dorsalis pedis- SBP is highest, DBP is lowest) ◦ BP cuff at level of heart- most accurate reading BP cuff above level of heart- false low ‣ BP cuff below level of heart- false high
79
What happens if the blood pressure cuff is above the heart?**
It gives a false low reading.
80
What happens if the blood pressure cuff is below the heart?**
It gives a false high reading.
81
What is the function of automated blood pressure devices?
They use the oscillometric method to measure systolic, diastolic, and mean pressures.
82
why do STAT BP cycles cause inaccuracies
doesn't give arm time to be reperfused and causes inaccuracies

What are indications for an arterial line?
Critically ill patients multiple lab testing cardiac disease controlled hypotensio and major surgery.
84
What is Allen's Test used for?
To test for collateral flow via the ulnar arch.
85
What are the results of Allen's Test?
Return of color within 6 sec indicates a patent ulnar arch; delay of 7 to 10 sec indicates slow arch filling; 10 sec or greater indicates incomplete arch.

20g Angio/arrow. arm board iodine/ETOH wipe 4x4 Tegaderm 1% Lidocaine glove glasses transducer setup.
87
What is the technique for inserting an arterial line?
Arm on arm board, dorsiflexed, palpate radial artery, clean, inject local, insert catheter at 45 degrees, advance until flash, then change angle to 30 degrees.
88
